Once upon
a time, people used to get paid with pieces of paper and coins 
physical money  and take that to a building nearby, their bank
branch, for safekeeping. Nowadays the idea of a physical bank branch
is disappearing as it becomes increasingly irrelevant. And physical
money is used less and less. Transactions are handled in near-real-time,
increasingly initiated on smart phones. With the growing options in
digital transactions and digitally based money, will banks even be needed
in the future? - Paul Holister
